Description
Oxbryta (voxelotor) is a medication used to treat sickle cell disease (SCD). This medication works to increase the hemoglobin’s ability to bind and release oxygen, which helps to reduce sickling and improve blood flow in patients with SCD.
Uses:
Oxbryta is used to reduce sickling and improve blood flow in adult and pediatric patients with SCD.
Storage Conditions:
Oxbryta tablets should be stored at room temperature, between 20°C to 25°C (68°F to 77°F), in the original package. The medication should be kept away from heat, moisture, and light.
Mechanism of Action:
Oxbryta targets the hemoglobin molecule, increasing its affinity for oxygen and reducing its ability to polymerize, which leads to sickling and vaso-occlusion. By increasing the oxygen-carrying capacity of hemoglobin, Oxbryta helps to reduce sickling and improve blood flow.
HOW TO USE:
Oxbryta is taken orally, once daily, with or without food. The tablets should be swallowed whole and not crushed or chewed. The dosage of Oxbryta is based on the patient’s weight.
Precautions:
• Oxbryta may cause methemoglobinemia, a condition where the blood contains abnormal levels of methemoglobin. Patients should be monitored for signs and symptoms of methemoglobinemia, such as shortness of breath, fatigue, and cyanosis.
• Patients with glucose-6-phosphate dehydrogenase deficiency may have an increased risk of hemolysis when taking Oxbryta.
• The use of Oxbryta in pregnant women is not recommended.
Drug Interactions:
Oxbryta may interact with other medications that affect the levels of methemoglobin or potentially increase the risk of methemoglobinemia. Patients should inform their healthcare provider of all medications, supplements, or herbal products they are taking before receiving treatment with Oxbryta.
Contraindications:
• Oxbryta is contraindicated in patients with a history of hypersensitivity to voxelotor or any of its components.
• The medication is contraindicated in patients with severe renal or hepatic impairment.
Overdose:
There is no known risk of an overdose of Oxbryta. Patients should seek medical attention if any unusual symptoms develop after taking the medication or if more than the recommended dosage is taken.
Adverse Reactions:
The most common adverse reactions associated with the use of Oxbryta include headache, diarrhea, and abdominal pain. Patients should contact their healthcare provider if they experience any unusual reactions while using Oxbryta.
In conclusion, Oxbryta is a medication used to treat sickle cell disease by increasing the affinity of hemoglobin for oxygen and reducing the ability to polymerize, which leads to sickling and vaso-occlusion. The medication is taken orally once daily and the dosage is based on the patient’s weight. Oxbryta may cause methemoglobinemia and should therefore be closely monitored in patients. The medication has several contraindications, drug interactions, and precautions to be considered before consumption, and patients should inform their healthcare provider about any medications they are taking. Common adverse reactions include headache, diarrhea, and abdominal pain.
